Definitions

  • the present invention concerns dual rails for load carrying pallets provided with wheels and for which the wheels of at least one pair of the two wheel pairs are swiveling.
  • the pallets also may be fitted with walls and roof lending support to the load.
  • these load pallets of various types shall be called roller pallets.
  • roller pallets on conveyors and tracks are at present accomplished with the aid of guide rollers located on both sides of the conveyors, so that steering is directly by the edges of the roller pallets. This type of steering is complicated and expensive.
  • the object of the invention is to provide a new type of dual rail transportation system on which it is possible to transport roller pallets provided with at least one swiveling pair of wheels without any additional guiding means.
  • the dual rails of the invention are characterized in that on the margins of the running surface of one rail have been provided upwardly pointing, comparatively low guiding or steering flanges, with a spacing between them slightly greater than the breadth of the wheel running on the rail.
  • the other rail has a wider and substantially flat running surface, which is sufficiently wide to permit swiveling the pallet wheel running thereon. With the aid of the invention, the pallet swiveling wheels will be steered by the rails without the major friction and blocking which are caused by other kinds of steering of the swiveling wheels.
  • a favorable embodiment of the invention is characterized in that the height of the steering margin of the one rail has a ratio to the wheel diameter running thereon of about 1:20. Experiments have shown that a flange this low is very well able to steer the swiveling wheels into the direction of travel for a roller pallet.
  • Another embodiment of the invention is characterized in that the spacing between the rail steering margins has a ratio to the wheel breadth running thereon about 37.36. Experiments have likewise shown that a comparatively small clearance between the wheel and the steering flanges of the rail keeps the wheels continuously correctly steered.
  • a third embodiment of the invention is characterized in that on the upper margins of the steering flanges have been provided wheel positioning flanges pointing outward at an angle about 45°. These positioning flanges guide the swiveled wheels entering the rails, down in between the steering flanges, and they prevent derailing the roller pallet when a wheel is in a swiveled position.
  • FIG. 1 presents a side elevation view of a roller pallet supported on the rails.
  • FIG. 2 shows the section of the rails and wheels taken along line II--II in FIG. 1.
  • the wheels 2 of one wheel pair for the roller pallets on the dual rails are swiveling wheels having an offset dimension "c" shown between the horizontal axis of the wheel and the vertical axis of the wheel swivel shaft.
  • the wheels 3 of the other wheel pair are fixed i.e., are not swiveling.
  • On the margins of the horizontal running or traveling surface 5 of one rail 4 have been provided comparatively low steering flanges 6, their spacing a being slightly greater than the width b of the wheel.
  • the height h of the steering flange 6 has a ratio about 1:20 to the diameter d of the wheel traveling on the running surface 5.
  • the height of the steering flange 6 should be about 5 mm.
  • the distance a of the steering flanges from each other relates to the breadth of the wheel travelling therein as a ratio about 37:36. These figures may also represent dimensions in millimeters if the wheel diameter is about 100 mm.
  • On the top edges of the steering flanges 6 have been provided positioning flanges 7 for the wheel 2, pointing outward at an angle of about 45°.
  • the other rail 4a has a wider substantially flat running surface, which is sufficiently wider than running surface 5 of the one rail 4 to permit swiveling of the wheel 2a traveling thereon without the wheel falling off either edge of the rail.
